Red onions are a popular choice for UK growers due to their vibrant colour, mild to sweet flavour, and versatility in salads, cooking, and storage.

Varieties like Red Baron and Ruby Red are widely available, with Red Baron earning the RHS Award of Garden Merit for its strong flavour and reliable performance.

They thrive in well-drained soil and full sun, with planting times ranging from early spring to late summer for succession cropping, or autumn sowing for overwintering. The UK red onion season runs from late August to June, with many varieties storing well into the following year when cured properly.
